How can this query hard coded in phpMyAdmin to test:

SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG( TL_Avg ) AS Final_Grade
FROM atlas_tl_session_grades sg
JOIN atlas_tl_session s ON ( s.Session_ID = sg.Session_ID )
WHERE s.Course_ID = 'CL00000011'
GROUP BY sg.SOMS_KEY



gives me 104 records which is what I want.

Yet this next query inserts 312 records?

$insertgrades = $db->sql_query("INSERT INTO ".$prefix."_tl_course_grades (Course_ID, SOMS_KEY, UID, Academic_Year, Final_Grade)". "SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG(TL_Avg) AS FinalGrade
FROM ".$prefix."_tl_session_grades sg
JOIN ".$prefix."_tl_session s ON (s.Session_ID = sg.Session_ID)
WHERE s.Course_ID = '$Course_ID'
GROUP BY sg.SOMS_KEY");
if (!$insertgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }   


I have 104 students with grades. 3 grades per student in session_grades. I need to average the TL_Avg field for all 3 records and insert this record into course_grades.

Did you enter in the second query correctly?


$insertgrades = $db->sql_query("INSERT INTO ".$prefix."_tl_course_grades (Course_ID, SOMS_KEY, UID, Academic_Year, Final_Grade)". "SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG(TL_Avg) AS FinalGrade
FROM ".$prefix."_tl_session_grades sg
JOIN ".$prefix."_tl_session s ON (s.Session_ID = sg.Session_ID)
WHERE s.Course_ID = '$Course_ID'
GROUP BY sg.SOMS_KEY");
if (!$insertgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }   


You won't be able to combine those 2 queries and there is a syntax error.

Do you have the insert query inside of the loop? Or is seperate from the select query?

The second query "SELECT..." is correct as it gets all 104 records that I want. If I can't combine these two then can I separate them into something like:

$getgrades = $db->sql_query("SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG(TL_Avg) AS FinalGrade
FROM ".$prefix."_tl_session_grades sg
JOIN ".$prefix."_tl_session s ON (s.Session_ID = sg.Session_ID)
WHERE s.Course_ID = '$Course_ID'
GROUP BY sg.SOMS_KEY");
if (!$getgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }   
while($row = $db->sql_fetchrow($getgrades)) {
$Course_ID = $row[Course_ID];
$SOMS_KEY = $row[SOMS_KEY];
$UID = $row[UID];
$Academic_Year = $row[Academic_Year];
$FinalGrade = $row[FinalGrade];

$insertgrades = $db->sql_query("INSERT INTO ".$prefix."_tl_course_grades (Course_ID, SOMS_KEY, UID, Academic_Year, Final_Grade)". "VALUES ('$Course_ID', '$SOMS_KEY', '$UID', '$Academic_Year', '$FinalGrade')");
if (!$insertgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }
      
}         


Unfortunately this give me the same 312 records as the last attempt did.

Maybe you misunderstood me, the second code box in your first post has this query:



$insertgrades = $db->sql_query("INSERT INTO ".$prefix."_tl_course_grades (Course_ID, SOMS_KEY, UID, Academic_Year, Final_Grade)". "SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG(TL_Avg) AS FinalGrade
FROM ".$prefix."_tl_session_grades sg
JOIN ".$prefix."_tl_session s ON (s.Session_ID = sg.Session_ID)
WHERE s.Course_ID = '$Course_ID'
GROUP BY sg.SOMS_KEY");
if (!$insertgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }   


Please look at that again and verify that it is correct.

Also try this and paste the the output in your response:


$getgrades = $db->sql_query("SELECT Course_ID, SOMS_KEY, UID, Academic_Year, AVG(TL_Avg) AS FinalGrade
FROM ".$prefix."_tl_session_grades sg
JOIN ".$prefix."_tl_session s ON (s.Session_ID = sg.Session_ID)
WHERE s.Course_ID = '$Course_ID'
GROUP BY sg.SOMS_KEY");
if (!$getgrades) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
}   
while($row = $db->sql_fetchrow($getgrades)) {
   $grades[] = $row;
}
print_r($grades);

It looks ugly.

This ran in phpMyadmin

INSERT INTO atlas_tl_course_grades( Course_ID, Course_Number, SOMS_KEY, UID, Academic_Year, Final_Grade )
SELECT Course_ID, Course_Number, SOMS_KEY, UID, Academic_Year, AVG( TL_Avg ) AS FinalGrade
FROM atlas_tl_session_grades sg
JOIN atlas_tl_session s ON ( s.Session_ID = sg.Session_ID )
WHERE s.Course_Number = '543'
GROUP BY sg.SOMS_KEY


..results in 104 records inserted.

This


$insertgrades = "INSERT INTO atlas_tl_course_grades( Course_ID, Course_Number, SOMS_KEY, UID, Academic_Year, Final_Grade )
SELECT Course_ID, Course_Number, SOMS_KEY, UID, Academic_Year, AVG( TL_Avg ) AS FinalGrade
FROM atlas_tl_session_grades sg
JOIN atlas_tl_session s ON ( s.Session_ID = sg.Session_ID )
WHERE s.Course_Number = '$Course_Number'
GROUP BY sg.SOMS_KEY";
$sql = $db->sql_query($insertgrades);
if (!$sql) {
      echo("<p>Error performing query: " . mysql_error() . "</p>");
      exit();   
      }



results in 312 records inserted.

I have echoed the value for Course_Number and it is in fact 543. I don't understand why this statement ran in a PHP script would insert the same record 3 times resulting in 312, yet ran in SQL it inserts the correct 104 records once.

After banging away at this all day I found what was happening.

I had an extra set of
{

}

that was looping.
